TheDS4200 automatically and dynamically moves frequently accessed data to higher performing HDDsin the system without manually creating and managing storage tier policies.All Flash Array (AFA) capability: Meets the demand for higher speed storage and provide higherIOPs and bandwidth with lower power usage and total cost of ownership than hybrid or HDD-basedsolutions.RAID levels 0, 1, 5, 6, and 10 : Provide the flexibility to choose the level of data protection required.Virtualized storage pools: Enables rapid, flexible storage provisioning and simple configurationchanges. Stored data is distributed across all drive groups in the pool (wide striping) which helpsimprove performance, lower latency, and achieve higher volume capacities. When a new drivegroup is added to the pool, the system performs automatic rebalancing to utilize all drives in thepool for better performance.Thin provisioning: Optimizes efficiency by allocating drive storage space in a flexible manneramong multiple applications, based on the minimum space required by each application at anygiven time. With thin provisioning, applications consume only the space they are actually using, notthe total space that has been allocated to them, which allows clients to purchase storage they needtoday and add more as application requirements grow.SSD Read Cache: An extension of the controller's cache to improve performance of read-centricworkloadsLenovo ThinkSystem DS4200 Storage Array 14 |
